瓦斯涌出的地质构造控制因素分析

通过地质构造对瓦斯赋存的控制分析,煤巷掘进工作面小断层分布、断层性质、断层落差调查研究,利用矿井安全监测监控系统对煤巷掘进工作面迎头CH4浓度适时跟踪测定,着重分析研究了过断层期间小断层落差与迎头瓦斯涌出的关系,确定了唐口煤业掘进工作面瓦斯涌出受小断层影响的范围和峰值出现的距离,为预测煤巷掘进工作面的瓦斯涌出奠定了基础,对安全生产具有重要指导意义。

Analysis of Geological Tectonic Factors of Methane Gushing

With real-time methane density monitoring data,this paper analyzed the relationship of small fault throw and methane gushing during roadway driving through fault based on the analysis of geological tectonic controlling methane occurrence and statistic of small faults.It confirmed range of methane gushing influenced by small fault and gushing peak distance.The result provided base for the prediction of methane gushing in coal roadway driving.
